Question

我正在尝试使用pandas库中的.read_html（）函数，并在shell中运行代码时不断收到此错误。我看到你需要安装lxml所以我用apt-get做了。但后来当我试图再次运行时，我得到了同样的错误。

(trusty)mdz5032@localhost:~$ sudo apt-get -y install python-lxml
[sudo] password for mdz5032: 
Reading package lists... Done

python-lxml is already the newest version.

以下是我正在使用的代码

import pandas as pd
import pandas_datareader.data as web
import quandl


df = quandl.get("FMAC/HPI_PA", authtoken="")

fiddy_states = pd.read_html('https://simple.wikipedia.org/wiki/List_of_U.S._states')

我取出了api密钥，但如果需要可以发布。

这是完整的追溯

Answer 1

sudo apt-get install python3-lxml

您已为python2安装了lxml，但您的代码在python3下运行。

任何人都可以解释为什么我收到此错误[ImportError：找不到lxml，请安装它]
